' CAR-ROOF.

Application filed August 18, 1915. Serial No. 46,076.

' Improvement in Car-Roofs, ofwhich the following is a specification. K I

. The invention relates to outside car roofs and has for its objects certain improvements in the roof set forth in my application No. 19,902, filed April 8, 1915. These improvements relate more particularly to the combination, with the said structure of roof, of a ridge pole and purlins and filler barsin the same arranged to .carry the bodies of the roof sheets at a distance above the carline flanges, so that the depth of the roof sheet seam flanges and seams are reduced and the sheets strongly supported throughout. By this construction roof sheets of lighter metal are rendered efficient. I also simplify the formation of the seam flanges of the roof sheets, carrying them down vertically upon the outer sides of the side plates, and closing and supporting them by filler castings. This construction allows the carlines to be shortened and simplified, and they terminate on the tops of the side plates, without depending flanges; the roof sheets being strongly united with the carlines by double seam flanges which are of. arched formation and spaced apart, and the strong connection of the said flanges in arched or U-form with the vertical face of the side plate being suf ficient to take the place of such connection The improvements also relate to such other features of advantage as are inherent in the construction about tobe described.

With such objects in view, the invention consists in the parts and combinations thereof herein set forth and claimed.

.I order to make the invention more clearly understood I have shown in the accompanying drawings means for carrying the same into practical efl'ect, without limiting my improvements, in -their useful applications, to the particular construction which, for the purpose of explanation, .I have made the subject of illustration.

In said drawings Figure 1 is a top plan view of a car roof embodying the invention, portions of the same being broken away.

Fig. 11 is a vertical, section of one of the carline bolts.

Figs. 12 and 13 show an inner face View and a vertical section of the filler casting for the vertical parts of the roof sheet seams. Referring to the drawings, the upper part of the car body frame, .which is the supportcomprises side plates of Z-bar cross section, each side plate consisting of a vertical longitudinal web 1, an inwardly extending top horizontal flange 2 and an outwardly extending bottom horizontal flange 3, the latter acting as a substitute for a fascia for protecting the eaves portions of the roof, especially the projectarched roof sheet seams. These side plates are united at the ends of the car by end platest of suitable character, preferably of the form shown, which are arched from side plate to side plate across the car and comprise an arched flange 5 extending inwardly from the end of the car and terminating in of one of the carare supported by suitable posts 10 and braces I i 11, which rise from the sills-(not shown) and are united withthe flanges 3 and 9 by brackets 12. The saidend sheathing and the side sheathing 13 are attached to the inner sides of the upright members of the car body frame, and extend up against the inner faces of the side plate webs 1 and of the 5 end plate member 7. v

At suitable intervals along the side lates are arranged carlines 14 which are arched across the ridge, from side plate to s1de plate. Each carline has in cross section the .10 form of an inverted channel bar of U or trough-likeshape (Fig. 6) having vertical webs or flanges 15, a connecting top web 16 and outwardly extending bottom side flanges 17. The ends of the carline are formed with horizontal flanges 18, which are continuations of the flanges 1'7, andwhich rest on the side plate flanges 2 (Fig. 10), the carline terminating at about the vertical planes of the side plate webs 1. The flanges 18 20 may be extended or spread longitudinally of the car as seen in Fig. 7.

The carline is or may be die-formed of one ""integral piece of heavy sheet metal, being pressed into the permanent form shown.- The flanges 18 are perforated at 19 for riveting to the side plate flanges 2 at 20. The side flanges of the carline are perforated at 21 for the attachment .of the longitudinal roof frame members, and the webs 16 at 22 for 0 the attachment of the roof sheets.

, The roof frame also comprises longitudinal frame members, consisting of a ridge pole 23 and purlins 24. Or the ridge'pole 23 may be omitted and more purlins added. These members are in the form of U-channel bars with horizontal sid'e flanges 25. These flanges are applied to-the under sides of the' carlines and are riveted at 26 to the side flanges 17 of the carlines through the perforations 21. In the channels of these members 23, 24 are fitted filler bars 27 of wood (which may be about two by two, and a half inches in cross section) which extend from carline to carline (see Figs. 5 and 6). These "bars extend about half way up the sides of parts abut the flanges 17 and their 'upper parts extend to the-webs 15. p The roof sheets 28 (Fig. 9) are formed at their side edges .with seam flanges comprising preferably vertical flanges 30 which are vertical carline webs 15, and these flanges are continued into horizontal flanges '31 which overlie the horizontal top webs 16 of the carlines. i The flange 31 atone edge of the sheet is immediately next to the carline, and terminates in an upturned supporting andwater excluding lip 32. The upper and- 35 outer flange .31 terminates in a downwardly bars 27.

extending'flange 33, and a horizontal lip 34 which rests on the top of the next roof sheet. The flanges 30, 31, 33 of the exterior overlapping roof sheet edge-thus constitute a water tight seam cap. The outer flange 31 is strongly supported-by collars 35 which are integral with the carline bolts 36 (Figs. 6 and 11), and the head portion 37 of such bolt, before it is headed, is passed up through a perforation 38 in the flange 31, and is there riveted down into a head 39. The lower threaded part of the bolt passes down through a perforation 4O I 9) in the lower and inclosed flange 31 of the next roof sheet, and then through a perforation 22 of the carline, and there receives a nut 41 which is arranged in the channel of the carline' Nut locks 42 are preferably used with the nuts 41. The seam portions of the two meeting roof sheets are thus spaced part, and both are rigidly and independently united with the carline, forming a strong and braced seam'and cap. I prefer to employ four of the bolts 36 along the arch of the carline, at the places indicated by the perforations 22 in Fig. 7. The two bolts near and at each side of the ridge also embrace the saddle 43 for the running boards 44 (Fig. 6), said saddle being thereby bolted down on the seam cap portions of the roof sheets. One.edge of the saddle 43 is curved to conform. to the arch of the seam (Fig. 3) and the other side is flat and horizontal and on the latter side the boards are secured by bolts 45. The heads of those bolts 36 -which 100 do not include the saddle,.rest directly on the I seam flange 31.

The end roof sheets- 46 terminate at one edge in a depending flange 47, and at" the other edge one of them terminates in a lip 32 and the other in a flange 33 and lip 34. Each of these end roof sheets is supported at the end of the car by a fascia 48 bolted to the end plate 4 so as to extend'above the flange 5 and be flush with the tops"-of-the filler The filler casting 49 for the depending portions of the seams is shown in Figs. 12 and 13. It is ofa shape and size to fit within" the flanges 30, 30, 31; that is to say it corresponds with the carline webs15, 15,16. It is perforated at 50 to receive a through bolt 51 which passes from the outside of the flange 31 totheinsideof the side plate web 1 ig.'. 10). This casting is preferably cored out as indicated to lighten it. or may be in contact with the sides of the The depending eaves portions of the roof side plates by bolts 52.
